SEALING SOLUTIONS

With its broad chemical resistance, Chemraz® 551 is ideally suited as a universal sealing material for aqueous semiconductor wafer processing and chemical/DI water distribution systems. Chemraz® 551 provides a significantly wider operational band and superior compression set resistance than any other broad range perfluoroelastomer (FFKM) on the market. With an upper temperature limit of 316ºC (600ºF), it is the elastomer of choice for the most demanding applications from Ozonated DI water to Hot Sulfuric Resist Strip.

Chemraz® 551 is one of Greene, Tweed’s many cost-effective products and services that increase the reliability and extend the lifetime of our customers’ equipment in challenging aqueous conditions while protecting both the operator and the environment from harmful fluid leaks.

Features & Benefits

  • Broad chemical compatibility
  • High temperature capability (up to 316ºC/600ºF)
  • Excellent compression set maintains seal integrity in wide temperature and pressure variations as well as vibration
  • Breadth of capabilities allows for standardization on one material and reduces inventory line items
  • Longer and better seal integrity in seal applications lower overall equipment Cost of Operation (CoO)

APPLICATIONS

  • Valve seals
  • Fitting and union seals
  • Gaskets
  • Regulator seals
  • Filter seals
  • Dispensing seals
